Prism’s Competitive Advantage
Prism PV Module
• Lower cost solar modules ($1.36/watt)
• 29-72% less solar cells.
• Planar concentrator
• Intelligent - Passive “tracking” – (no
moving parts).
• Single-crystal stability with thin film costs.

Competitor PV Modules
• Expensive modules ($3.20/watt)
• Serious silicon shortage to continue.
• Traditional concentrators
• Requires extensive cooling and
expensive/precise mechanical tracking.
• Thin films have largely not met cost
projections over two decades and crystalline
remains a costly and an inefficient use of
2
silicon.
